Facial Recognition: Advantages and Disadvantages

The system specifically uses a combination of mathematical analysis and artificial intelligence , particularly machine learning algorithms, for the collection, storage, and retrieval of biometric data, as well as other sensing imaging techniques to include photometry and LiDAR or light detection and ranging , among others. Central to the advantage of facial recognition is that it enables the computerized and automated processing of biometric data based on the digital image or live video feed of a person for a variety of purposes or applications. It can be used as a part of identification and access control systems in organizations, as well as personal devices, such as in the case of smartphones. Consider Facebook as an example. Through machine learning and Big Data analytics , the social networking site can recognize photos of its users and allow automated linking or tagging to individual user profiles.

Facial Recognition: Advantages and Disadvantages

A facial recognition system is a technology capable of matching a human face from a digital image or a video frame against a database of faces, typically employed to authenticate users through ID verification services , works by pinpointing and measuring facial features from a given image. While initially a form of computer application , facial recognition systems have seen wider uses in recent times on smartphones and in other forms of technology, such as robotics. Because computerized facial recognition involves the measurement of a human's physiological characteristics facial recognition systems are categorised as biometrics. Although the accuracy of facial recognition systems as a biometric technology is lower than iris recognition and fingerprint recognition , it is widely adopted due to its contactless process. Automated facial recognition was pioneered in the s. Their early facial recognition project was dubbed "man-machine" because the coordinates of the facial features in a photograph had to be established by a human before they could be used by the computer for recognition. On a graphics tablet a human had to pinpoint the coordinates of facial features such as the pupil centers, the inside and outside corner of eyes, and the widows peak in the hairline.

Facial recognition technology has a lot of applications that can be advantageous and disadvantageous. Face recognition technology has always been a concept that lived in fictional worlds, whether it was a tool to solve a crime or open doors. Today, our technology has developed this field significantly as we are seeing it become more common in our everyday lives. What exactly is facial recognition and how does it work? Facial recognition is a type of biometric software that is able to identify or verify a person from a digital image by mapping out their features mathematically and saving the information as a fingerprint.

With the advancement of technologies each and every day, humanity is slowly going towards contactless everything. One such advancement will be the facial recognition technology or the FR tech, which is the prime focus of this article. Facial recognition technology is a system or software which is capable enough to verify the identity of a person from analyzing an image or video footage. Some of the technologies or software are so advanced that even blurred pictures are sometimes rendered enough and analyzed to know the identity of the person. So much are the advantages of this system that it would take a long article to note down each and every one of them.


Faces are complex and multidimensional which makes extraction of facial features to be very challenging, yet it is imperative for our face recognition systems to be.


Facial recognition system

Face recognition, as one of the most successful applications of image analysis, has recently gained significant attention. It is due to availability of feasible technologies, including mobile solutions. Research in automatic face recognition has been conducted since the s, but the problem is still largely unsolved.

The pros and cons of facial recognition technology

Over the past few decades, interest in theories and algorithms for face recognition has been growing rapidly. Video surveillance, criminal identification, building access control, and unmanned and autonomous vehicles are just a few examples of concrete applications that are gaining attraction among industries. Various techniques are being developed including local, holistic, and hybrid approaches, which provide a face image description using only a few face image features or the whole facial features. The main contribution of this survey is to review some well-known techniques for each approach and to give the taxonomy of their categories. In the paper, a detailed comparison between these techniques is exposed by listing the advantages and the disadvantages of their schemes in terms of robustness, accuracy, complexity, and discrimination.

Plus, it's prime to see even more frequent use as time goes on. Like all technology, there are benefits and drawbacks to using facial recognition, and there's a lot of disagreement as to whether tr not facial recognition is worth the security issues that come with it. Facial recognition has many benefits in society, including increasing safety and security, preventing crimes, and reducing human interaction. It can even help support medical efforts, in some cases.

Facial recognition technology is generating lots of excitement. Yet, it is also very controversial around issues like privacy, reliability, possible bias and lack of regulation. As a result, businesses must beware of the potential disadvantages of facial recognition. There is much criticism about the use of facial recognition technology. Thus, interest groups tend to be very opinionated about it. Prominent companies of all sectors are making significant investments in facial recognition.
